Jorge L. Williams commented on XERCESJ-1562:
--------------------------------------------
Mukul Gandhi, mentioned the following on the list:
"As a workaround, I can find the following expression to be working
correctly though,
(xs:dateTime - xs:dateTime) le xs:dayTimeDuration"
Based on that I rewrote the schema to:
<schema
elementFormDefault="qualified"
attributeFormDefault="unqualified"
xmlns="http://www.w3.org/2001/XMLSchema";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";
xmlns:tst="http://www.rackspace.com/test/simple";
targetNamespace="http://www.rackspace.com/test/simple";>
<element name="test" type="tst:Duration"/>
<complexType name="Duration">
<attribute name="start" type="xsd:dateTime" use="required"/>
<attribute name="end" type="xsd:dateTime" use="required"/>
<assert test="(xsd:dateTime(@end) - xsd:dateTime(@start)) le
xsd:dayTimeDuration('P1D')"/>
</complexType>
</schema>
It's still not working correctly :-(

> Key: XERCESJ-1562
> URL: https://issues.apache.org/jira/browse/XERCESJ-1562
> Project: Xerces2-J
> Issue Type: Bug
> Components: XML Schema 1.1 Datatypes
> Affects Versions: 2.11.0
> Reporter: Jorge L. Williams
>
> I'm working off of the latest 1.1 branch. I have the following schema:
> <schema
> elementFormDefault="qualified"
> attributeFormDefault="unqualified"
> xmlns="http://www.w3.org/2001/XMLSchema";
> xmlns:xsd="http://www.w3.org/2001/XMLSchema";
> xmlns:tst="http://www.rackspace.com/test/simple";
> targetNamespace="http://www.rackspace.com/test/simple";>
> <element name="test" type="tst:Duration"/>
> <complexType name="Duration">
> <attribute name="start" type="xsd:dateTime" use="required"/>
> <attribute name="end" type="xsd:dateTime" use="required"/>
> <assert test="xsd:dateTime(@end) le (xsd:dateTime(@start) +
> xsd:dayTimeDuration('P1D'))"/>
> </complexType>
> </schema>
> Essentially, I want to make sure that the duration between start and end is
> not longer than one day. I test against two documents (using options -fx and
> -xsd11 on the CLI validator):
> good.xml
> <test xmlns="http://www.rackspace.com/test/simple";
> start="2012-03-12T11:51:11Z" end="2012-03-13T11:51:11Z"/>
> this document should validate. And
> bad.xml
> <test xmlns="http://www.rackspace.com/test/simple";
> start="2012-03-12T11:51:11Z" end="2012-03-13T11:51:12Z"/>
> which should trip the assertion.
> Unfortunately xerces fails both documents, which looks like a bug to me
> especially since Saxon passes good.xml but fails bad.xml.
